The outgoing Speaker of the House of Commons has called the prorogation a “constitutional outrage” and vowed to allow for “procedural creativity” to prevent the prime minister defying a new law designed to block a no-deal Brexit. Mr Bercow, who has repeatedly been accused of siding with Remain-backing MPs, told a gathering at the University of Zurich on Thursday that a second EU referendum “could happen”.
On Thursday the Supreme Court heard a submission from the former Tory prime minister Sir John Major in the case brought against the government by anti-Brexit campaigner Gina Miller.
The court has been asked to determine whether the prime minister’s prorogation - which runs until October 14 - was unlawful.
The three-day hearing concluded yesterday and a decision is expected next week.
Eleven justices head appeals arising out of separate legal challenges in England and Scotland, in which leading judges reached different conclusions.
